The need for affordable and reliable prosthetics in low income countries is significant. Using 3D printers to manufacture prosthetics has proven to be a successful method. It is considerably cheaper than traditional manufacturing methods and allows for remote customization. Lindhe Xtend is a company that has been dedicated to developing high-quality prosthetics since 2013. The company was founded by Christoffer Lindhe, whose personal experience of losing both legs and an arm in a train accident in 2006 motivated him to start Lindhe Xtend. They now strive to be a leader in user-friendly prosthetics and distribute their range to specialized orthopedic clinics. Social sustainability is becoming an increasingly crucial aspect for companies. This case study aims to investigate whether a relatively new but groundbreaking company in its industry can use its knowledge to develop a product that benefits people beyond the company's usual target audience and users. Furthermore, the study has explored whether the innovation can lead to strengthening of Lindhe Xtend's original brand and understanding the obstacles or opportunities that an expansion of this kind may entail. The work is a qualitative study where semi-structured interviews have been conducted. The study applied a thematic analysis and was based on a modified version of the marketing mix, which helped analyze and categorize various aspects of the product and answer the research questions of the study. The conclusion is that the product expansion can strengthen or maintain Lindhe Xtend's brand. Lindhe Xtend should collaborate with aid organizations to create awareness about the product. Illustrated videos on digital platforms are also an alternative communication method.
